EMASCULATOME Harry 0. Snouffer, Deer Creek, Okla. Application March 25,1933. Serial No. 662,734 6 Claims. ('01. 128306) This invention relatesto an improved and structurally refined veterinarys emasculatome such asis used for castrating animals.

Generally stated, the'improved instrument in which my advantageousfeatures are embodied is of the well-known pincers type. Admittedly,this form of emasculatome is more or less universally employed in awell-known manner for pinching or crushing the spermatic cord in abloodless mannerand without developing an objectionable wound in thescrotum.

It is a matter of common knowledge however that the pincers-typeemasculatome, as well as the wrench typeis not altogether fool-proof andsuccessful in its completeness of action due to the-accidental slippageof the spermatic cord at the time it is supposedly pressed between the.

crushing jaws.

'I am aware of the fact that it is not broadly new to provide asupplemental means to aid in. holding the cord effectively in placewhile performing the operation. Notwithstanding these previous attemptsto solve'the problem of successfully holding the cord whileperforming'this delicate task, I have-evolved and produced anappreciable contribution to the art which, to my mind, is more positiveand dependable inaction, insures more expeditious and effective results,and better fulfills the requirements of an instrument ofthisclassification.

Other features and advantages of the invention will become more readilyapparent from the following description and drawings.

' In the drawings:

Figure 1 is an enlarged perspective view illustrating the essentialfeatures of the'unique cord holding and retaining means constituting theprincipal novelty of the invention.

Figure 2 is a view in section and elevation showing the complete toolwith the cord grasping jaws closed and the master or severing jawsapproaching a substantially closed position.

Figure 3 is a front end elevation of the arrangement depicted in Figure2.

Figure 4 is a detail perspective view.

Figure 5 is a' view similar to Figure 2 showing both sets of jaws wideopen to permit insertion of the testicles.

Figure 6 is a view showing the final step wherein both sets of jaws arepositively closed.

I will first describe the well known pincers type castrating instrumentor emasculatome as it is generally known in the trade and profession. Tobegin with, the numeral '7 designates the conventional operating levershaving handgrips 8 jaw and having their opposite end portions pivotallyjoined together asat 9. The main or master cord severing jaws as theyare known in the trade are denoted by the numerals 10 and terminate inthe customary fashioned blunt grip.-

ping edges 11. g p 7 These jaws are pivotally attached to each other incompanion relationship as indicated at 12 ,and' have their shankportions 13 pivotally connected as at 14, to the adjacent end portionsof the levers '7 outwardlyof the main pivot 9. There is absolutelynothing new in this type of an instrument. I

In accordance with my. invention, I provide a pair of duplicateattaching lugs or ears 15 on 70,: the inner peripheral portion of thejaws 10 at points adjacent to and on opposite sides: of the pivot 12.These lugs are adapted to accommodate the .supplemental cord graspingand holding jaws 16.- These jaws 16 are of arcuateor seg- 7 mentalformation and have their attached ends bifurcated with the furcationsstraddling and pivotally attachedto the lugs 15 as indicated atthe'points 1'7. r I a It will be, noticed that the curvature of the 80.jaws 16 is slightly more acute than. the jaws 10 and that the jaws 16are confined; wholly within the limits of the jaws 10. Moreover, theabutting free swingable edge portion 18 of these supplemental jaws arefashioned to come together in firm contacting relationship as is obviousfrom the configuration illustrated in Figure 1. Then too, the edgeportions 18 are provided with cooperating notches 19 which are broughttogether in matched relationship to provide a sort of a keeper for thespermatic cord. The numeral 20 designates spring retention studs carriedby the intermediate outer faces of the jaws 16 and located toaccommodate the inner ends of the coiled expansion and compensatingsprings 21.

The outer ends of the springs 20 are located in sockets formed in theintermediate inner faces of the jaws 10 as shown in Figure 2, thesprings co-operating with reduced terminals 22 carried by the springadjusting set screws 23; Manifestly the set screws are threaded throughopenings in alinement with the sockets and under this arrangement it ispermissible to regulate the tension of the springs 21 to the requisitesensitivity of action.

Under this arrangement the cord holding or supplementary jaws 16 aremaintained in substantially spaced parallelism with respect to the jaws10 and as before stated the curvature of said jaws 16 is such that theycome together without necessarily forcing the jaws 16 together in anundesirable rigidly crushing manner. Even if the jaws 16 are pressedtogether firmly because of improper adjustment of the respective jaws 10and 16, the registering notches 1 9 afford the desired clearance actionfor the spermatic cords.

It is apparent that when the levers 7 are spread apart in therelationship depicted in Figure 5 both sets of jaws 10 and 16 areequally spread apart to permit initial placement of the instru-- ment.Then by moving the levers together the jaws are simultaneously movedtogether in the desired intermittent manner so that when the levers '7arein the position shown in Figure 2 the jaws 16 have been broughttogether sufficiently close' to grasp and hold the spermatic cordwhereby when the levers approach the relationship shown in Figure 6 thejaw-ends 11 will come into proper cord severing or crushing coaction.

It is thought from the foregoing description that the advantages andnovel features of the.

invention will be readily apparent. It is to be understood that changesmay be made in the construction and in the combination and arrangementof the several parts provided that 'such changes fall within the scopeof the appended claims.

I claim: I 1. An emasculatome of the class described comprising a pairof pivotally connected cord crushingjaws, operating levers for saidjaws,and a pair of duplicate spr ng-pressed cordholding elements carriedby said jaws, and compensating spring means associated with the jaws andsaid elements to bring the effective portions of said elementsinto cordengaging and holding relationship prior to the final closing action ofthe jaws.

2. An emasculatome of the class described comprising a pair of pivotallyconnected cord crushing jaws, a pair of operating levers for said jaws,and a pair of adjustably mounted supplementary jaws carried by the firstnamed jaws and co-operating with the inner peripheral surfaces of saidjaws, sa d supplementary jaws being mounted to move into initial cordholding relationship prior to the final closing of the firstnamed jaws.

3. A pincers type emasculatome comprising a pair of pivotally connectedsubstantially semicircular master cord crush ng jaws, a pair ofoperating levers for said jaws, a pair of supplementary smaller cordengaging and retaining jaws pivotally attached to'the inner portions ofsaid first-named jaws.

4.-A pincers type emasculatome comprising a pair of pivotally connectedsubstantially semic rcular master cord crushing jaws, a pair ofoperating levers for said jaws, a pair of supplementary smaller cordengaging and retaining jaws pivotally attached to the inner portions ofsaid first-named jaws, the free ends of said supplementary jaws beingnotched to form an opening to accommodate the spermatic cord.

5 A pincers type emasculatome comprising a pair of pvotally connectedsubstantially semicircular master cord crushing jaws, a pair ofoperating levers for said jaws, a pair of supplementary smaller cordengaging and retaining jaws pivotally attached to the inner portions ofsaid first-named jaws, the free ends of said supplementary jaws beingnotched to form an opening to accommodate the spermatic cord, and springmeans interposed between the respective pairs of jaws to render thesupplementary jaws substantially resilient in action. 1

, 6. A pincers type emasculatome comprising a pair of substantiallysemi-circular outer cord crushing jaws pivotally connected together,operatng levers for said jaws, said jaws being provided on their innersurfaces at predetermined points with attaching lugs, a pair of opposedsubstantially semi-circular smaller supplementary jaws located withinthe limits of said first-named jaws and pivotally attached at one end tosaid lugs, the free ends of sa d supplementary jaws being notched,coiled springs interposed between the respective-opposed pairs of jaws,and spring tensioning means carried by the first-named Jaws.
